The,.psoutache isv therefore accurately, positioned on thegoods by guiding the: line of stitching, and as the stitching does'notex-v tend transversely through the soutache, any color of threadmay. be ,usejd with any1 color of .vsoutache, and thegsoutacheqwill ser`curely attached to the goods'and not disfigi uredv by the'- thread."With my lirnpr'ovements, therefore, .I am-enabled` to attach lsoutacheto thegoodsby aninvisiblejstitch andk carry out the operationrapidly and accurately.
